Sleeping Bear Dunes Michigan, USA Travel Guide
Spring (April-May): Temperatures typically range from the 40s to 60s Fahrenheit (4-18°C). The weather can be variable, with cool days, occasional rain, and lingering chill from Lake Michigan. Expect fewer crowds, fresh air, and the first signs of green. Wildflowers begin to appear in late spring. Nights remain cool, often needing a light jacket or fleece.
Summer (June-August): These are the warmest months. Daytime temperatures usually sit in the 70s and 80s Fahrenheit (21-29°C), with cooler evenings dropping into the 50s. Humidity levels can be high at times. Summer brings the highest chance of thunderstorms, which can be intense but usually pass quickly. This period is ideal for swimming and all water activities due to warmer lake temperatures.
High Season (June-August): Warmest weather, all park facilities are open, good for swimming and water sports, longest daylight hours. Most crowded period, accommodation prices are highest, needs booking well in advance. Popular spots like the Dune Climb can be very busy.
Shoulder Season (May, September-October): Fewer crowds compared to summer, pleasant temperatures for hiking and exploring, lower accommodation prices (especially in May and late October), beautiful fall colors in autumn. Some facilities may have limited hours (specifically early May and late October). Lake Michigan water is still cold in May and cools rapidly in October, limiting swimming. Ferry service to the islands may operate on a reduced schedule.

An approved ESTA is generally valid for two years or until your passport expires.

The United States Dollar (USD, denoted by $) is the currency used. Credit and debit cards are widely accepted throughout the region, but carrying some cash for small purchases or emergencies is always a good idea. ATMs are readily available in nearby towns.
